Which service supports browsing and searching in Tableau?

The service that supports browsing and searching in Tableau is the VizPortal. This service serves as the interface for users to access and interact with Tableau Server content and resources. It allows users to search for workbooks, data sources, and other content deployed on the server. The VizPortal is essential for providing a user-friendly environment where users can discover and browse through published assets efficiently, facilitating increased collaboration and data utilization within the organization.

The Data Server, while it provides capabilities for data management and connecting to data sources, does not directly handle user interface navigation or searching capabilities. The Application Server focuses on the functionality required for user sessions and managing connections to the server applications, but it does not directly provide browsing features. The Backgrounder service is responsible for running extract refreshes and scheduled tasks, which supports data processing behind the scenes but does not contribute to content searching or browsing functionality. Thus, VizPortal is the primary service designed specifically for the user experience related to discovering and accessing Tableau content.
